"Create A Fatality" is not a playable video game. It's a community term for inventing Mortal Kombat-style finishing moves—purely imaginative.
Character: Cybernetic ninja with plasma whip
Fatality: Whip wraps enemy's neck → lifts them → plasma severs head → catches head mid-air → whip retracts into arm cavity
Sounds: *Zzzzt* (whip), *Schlk* (sever), *Thwip* (catch), *Hiss* (retract)
It's creative writing + game design practice—no code required.
